Data Sheet

6
The majority of the problems you find at a typical cell site are caused by problematic cables, pinched cables, corroded connectors,
antennas, lightning strikes, rain getting into cables, and bullet holes. Degraded cable systems and badly positioned antennas affect
overall system coverage and eventually result in dropped calls. Site Master’s FDR-based return loss and DTF measurements can
pinpoint an antenna problem from ground level in a few seconds, enabling Site Master to identify small problems before they
become big problems.
RETURN LOSS / VSWR
Use the Site Master to make return loss and VSWR and verify that the cable and
antenna system conforms to performance specifications.
CABLE LOSS
Cable Loss metrics measure the level of insertion loss within the cable feedline
system. This measurement can be verified prior to deployment, when you have
access to both ends. Site Master automatically calculates the average cable loss.
DISTANCE-TO-FAULT
While the return loss metric is the best measurement to verify the health of a
system, distance-to-fault (DTF) is used to troubleshoot systems and locate the
problem.
The Site Master’s DTF measurement uses the fast Fourier transform to convert
frequency data to the time domain and displays signal anomalies with respect to
distance. Using the standard trace math feature, you can monitor small relative
changes over time.
2-PORT TRANSMISSION MEASUREMENTS (OPTION 21)
Cellular/PCS and 3G base stations today use diplexers, duplexers, and tower-
mounted amplifiers to extend the coverage area. Site Master’s 2-port transmission
measurement enables you to make gain, isolation, and insertion loss measurements
as well as verify sector-to-sector isolation.
BIAS TEE (OPTION 10)
The built-in bias tee can be turned on as needed to place +12 to +32V on the
center conductor of the RF in port, eliminating the need for you to carry external
supplies in the field.
